Corporate X is a fully responsive multipurpose theme for creating "content flexible" Drupal 7 websites in minutes. It's built over the most recent and recommended Drupal version: 7.21, so you can start from a "scratch brand new base" on building a long term support solution for your clients. Drupal Team currently recommends Drupal 7 due to the advance of its community modules above later versions, 1 year after its initial release, and this is one of Corporate X's highest features. You can browse the theme demo at Corporate X v 2.21 Demo. It’s extremelly easy to install, something like the "Next, next, next ..." way.
